We divide 43585863 by 354
We want to divide 43585863 by 354.

On to step 1:
354 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 354

Let's proceed to step 2:
The number 354 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Grab the next digit (5) from the dividend, add it to 43, then carry on: 435 / 354

Let's proceed to step 3:
When dividing 435 by 354, we get 1 with a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 354 from 435 and we're left with 81.
Grab the next digit (8) from the dividend, add it to 81, then carry on: 818 / 354

Advancing to step 4:
If we divide 818 by 354, we get 2 and a remainder of 110.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 110 after subtracting 708 from 818.
Append the next digit (5) from the dividend to 110 and continue with: 1105 / 354

Going ahead to step 5:
354 goes into 1105 3 times with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 123.0
The remainder is 43 after subtracting 1062 from 1105.
Grab the next digit (8) from the dividend, add it to 43, then carry on: 438 / 354

On to step 6:
If we divide 438 by 354, we get 1 and a remainder of 84.
Put 1 as the next digit of the answer. 
Result so far: 1231.0
The remainder is 84 after subtracting 354 from 438.
Fetch the next digit (6) from the dividend, attach it to 84 and continue: 846 / 354

Let's proceed to step 7:
846 divided by 354 is 2 with a remainder of 138.
Put 2 as the next digit of the answer. 
Result so far: 12312.0
If we subtract 708 from 846, we get 138.
Fetch the next digit (3) from the dividend, attach it to 138 and continue: 1383 / 354

On to step 8:
When dividing 1383 by 354, we get 3 with a remainder of 321.
The next digit of our result is 3. 
Result so far: 123123.0
If we take 1062 away from 1383, we end up with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

On to step 9:
354 goes into 3210 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 123123.9
If we take 3186 away from 3210, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
240 divided by 354 is 0 with a remainder of 240.
The number 0 becomes the next digit in our result. 
Result so far: 123123.9
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
2400 divided by 354 is 6 with a remainder of 276.
The next digit of our result is 6. 
Result so far: 123123.906
Deduct 2124 from 2400 and we're left with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 12:
If we divide 2760 by 354, we get 7 and a remainder of 282.
Write down 7 as next digit of the result. 
Result so far: 123123.9067
If we take 2478 away from 2760, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 13:
The number 354 fits into 2820 7 times, leaving a remainder of 342.
The number 7 becomes the next digit in our result. 
Result so far: 123123.90677
The remainder is 342 after subtracting 2478 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

The final outcome is 123123.90677, with a leftover of 0.000342.
